a few things could explain this, one the 26" tube is special order (kinda odd and screwy if it is considering that the website lists a 26" barrel fo the LE2), there has been a spec change and now the LE2 receives a 24" barrel just like the non-"LE" 10FPs, while the LE1 retains it's shorter 20" barrel (this possibility is actually quite likely, since it reduces the number of heavy barrel variations they have to warehouse), or there was a miscomunication somewhere and you have a Standard 10FP.
but by all means call savage and find out. but just to cover your own end of things take a close look and make sure that you were not shipped the wrong model first (just a suggestion, to cover ALL bases)
i will say that the 10FP with a 24" barrel in .223 is a VERY good shooter in my experience, if not for having to make a choice between food and keeping it, I would have never sold mine....
